Research progress of Codonopsis Radix and prediction of its Q-markers / 中国中药杂志

Codonopsis Radix is a traditional tonic medicine commonly used in China, which has the effects of strengthening the spleen and tonifying the lung, as well as nourishing blood and engendering liquid. The chemical constituents of Codonopsis species are mainly polyacetylenes, alkaloids, phenylpropanoids, lignans, terpenoids and saponins, flavonoids, steroids, organic acids, saccharides, and so on. Modern pharmacological studies showed that Codonopsis Radix also has a variety of pharmacological effects such as enhancing body immunity, protecting gastrointestinal mucosa and resisting ulcers, promoting hematopoietic function, regulating blood sugar, and delaying aging. In this paper, the chemical constituents of Codonopsis species and the pharmacological effects of Codonopsis Radix were summarized, and on this basis, the quality markers of Codonopsis Radix were analyzed. It was predicted that lobetyolin, tangshenoside I, codonopyrrolidium A, and the oligosaccharides were the possible Q-markers of Codonopsis Radix. This paper will provide scientific references for the quality evaluation and profound research and the development of Codonopsis Radix.

Evaluation of methodological and reporting quality of domestic clinical guidelines for hyperuricemia / 中国中药杂志

This study aims to evaluate the methodological and reporting quality of diagnosis and treatment guidelines for hyperuricemia as well as the expert consensuses and promote the understanding and application of the diagnosis and treatment guidelines for hyperuricemia. With "hyperuricemia" "guidelines" "consensus" "recommendations" as the key words in titles, the authors searched for the published clinical guidelines on hyperuricemia in Chinese against CNKI, Wanfang, VIP, Medlive and the official website of the industry association. The retrieval time limit was until May 31, 2021. The appraisal of guidelines for research and evaluation Ⅱ(AGREEⅡ) and the reporting items for practice guidelines in health care(RIGHT) were employed to evaluate the methodological quality and reporting quality of 14 guidelines/consensuses included. The average scores of the guidelines/consensuses were 80.85%(48.61%-98.61%) for the domain of scope and purpose, 34.52%(0-69.44%) for the domain of stakeholder involvement, 35.53%(6.25%-92.19%) for the domain of rigor of development, 55.85%(23.61%-86.11%) for the domain of clarity of presentation, 26.19%(0-76.04%) for the domain of applicability, and 21.42%(0-50.00%) for the domain of editorial independence. Nine guidelines/consensuses were of medium overall quality with grade B recommendation, and five guidelines/consensuses were of poor quality with grade C recommendation. The RIGHT classified the fourteen guidelines/consensuses into one of high reporting quality, three of medium reporting quality, and ten of low reporting quality. The results of this study indicate that the standardization and rigor of the methodological quality and the reporting quality of the clinical guidelines/consensuses for hyperuricemia in China remain to be strengthened.

Retrospective series of side-to-side ileosigmoidostomy shunting surgery for the treatment of slow transit constipation in elderly patients / 国际外科学杂志

Objective To evaluate the clinical and functional outcomes of Side-to-Side Ileosigmoidostomy Shunting Surgerys for the treatment of elder STC patients.Methods The clinical data of 67 patients all more than 63 years old with severe idiopathic STC treated with this novel approach between June 2010 and July 2017 were retrospectively analyzed.The perioperative complications and defection conditions were followed up by telephone and outpatient.The Wexner constipation score and gastrointestinal tract were compared before and after the operation.SPSS 19.0 software was used for statistical analysis.Independent sample t test was used for measurement data,t and x2 test were used for comparison of count data.Results All the patients received their operations successfully without deaths or serious complication.The center follow-up period (from outpatients or phone) was 12 months (6-29 months).only 16 patients developed complications including 2 and 14 total colonic exclusion.12 of the 14 got better obviously after enema and taken dynamic drugs,Only 2 patients with repeated abdominal pain and distention received jejunostomy.Six months after the operation,only 5 patients needed to take some drugs for defectation.Wexner constipation scores and Gastrointestinal Quality of Life Index (GIQLI) has improved obviously after 6 months and 12 months.Conclusions The novel surgical procedure,side-to-side ileosigmoidostomy Shunting Surgery that practised in our department,is an easy,safe and effective for the treatment of selected elderly patients with STC.Large-sample,randomized,controlled analyses are worth to investigate its clinical effects.

The Feasibility of Low Dose CT Scan in the Diagnosis of Pulmonary Tuberculosis / 实用放射学杂志

Objective To explore the feasibility and value of low dose CT scan for the diagnosis of pulmonary tuberculosis.Methods 150 patients with pulmonary tuberculosis underwent three doses CT scan (standard dose:150 mA;low-dose:15 mA and 30 mA) using GE dual slices helical CT.Besides the different tube current,other scan parameters including tube voltage,scan cycle,pitch,and collimation were the same in three dose groups.The scanned extent was from apexes to bases of lung.Image quality in standard group was compared with that in other two low dose groups and analyzed statistically by three radiologists.Results CT characteristics of pulmonary tuberculosis could be detected efficiently using low dose CT scan(30 mA) program,which was no significant as compared with the CT image using standard CT sose(P＞0.05).Howere,CT scan at 15 mA obviously affected on the diagnosis for both active and inactive pulmonary tuberculosis,the difference was significant (P＜0.05).Conclusion Low dose CT scan can replace totally the standard dose CT scan in diagnosing pulmonary tubercrulosis.
